Uncertainty analysis of humidity generator at negative temperature
In this paper,The negative temperature environment relative humidity generator which is developed by Changcheng Institute of Metrology & Measurement,AVIC was introduces.The relative humidity range of the generator is 10 %RH~95 %RH(-60℃~40℃).The uncertainty of the relative humidity of the generator is analyzed in detail.The careful consideration of the design and the use of high-precision sensors have played a significant role in reducing the uncertainty of relative humidity.The extended uncertainty of the humidity generator at negative temperatureis 2.8 %RH at-60 ℃ and 0.8 %RH at 40 ℃.
